SPECIlIFICATION forming p rt of Letters Patent No. 278,381, dated May29, 1883.

Application filed January 15, 1883. (No model.)

To all whom it may concern Be it known that we, WILLIAM 0. WHITE, ofLake Village, and WARRENDFHUSE, of Laeonia, in the dounty of Belknap andState of New Hampshire, have invented an Improved Steam-Trap and We dohereby declare that the following is a full and exact descriptionthereof, reference being bad to the accompanying drawings, making a partof this specification- -j l Figure 1 being acentral longitudinal ver-'tioal section of adouble steam-trap constructed with a part of ourimprovements; Fig. 2, a cross-section in a plane indicated by the lineas on, Fig. 1; Fig. 3, a cross-section in a plane indicated by the line3 y, Fig.1; Fig. 4, a

Our improved steam-trap in its simplest form, which we term aglobe-valve trap, is,

composed of a simple short pipe, in which the condensed steam collects,through which it passes, and from which it is discharged, acting, as tothe first part of our invention, in

combination witha fixed,'solid, plane-faced, or

I equivalently-formed valve-seat, against which one end of the said pipeor valve-stem abuts.

The said valve-pipe beinglocated in the open, air, and having nooperative mechanical connection whatever with the steam pipe or pipeswhich it drains, and not being affected by the contraction and expansionthereof, no additional valve action is required, and thevalvese'at'itself may be placed in the open air, being inclosed in acase or shell only for convenience in mounting, .and for attaching adrain-pipe to carry 0d the condensed water discharged from the trap. Forthese purposes, therefore, we

find it desirable to make the case or shell of Since in this inventionthe val ceedinglycheap in construction as well as effective inoperation.

As to the second part of our invention, it consistsin such a valve-pipeand asimilar solid, plane-faced, or equivalent form of seat, which ismovable, and connected by leverage with the valve-pipe, so that themotion resulting from the contraction and expansion of the pipe is alsocommunicated to the valve-seat in such a manner as to act in theopposite direction to that of the valve-pipe, the lever-cow nection alsobeing adjustable, so as to muliply the rapidity of the approach andseparation of the valve and seat to any extent desired. f

e-seat A (referring to the accompanying drawings) is always fixed, weare enabled, when desirable, to make one valve-seat serve for twovalvepipes, B B, as shown in Fig. 1, one valvepipe, B, abutting andshutting against one side, a, of the seat, and the other valve-pipe, B,abutting and closing against the other side, a, of the seat. Bothvalve-pipes may thus also be drained by one drain-pipe, (J. Thisprinciple may be carried still further to any practicable extent byhavin g three or more valve-seat surfaces in one and the same case D,facing in difierent directions. A single seat, however, may just as wellbe 'used, as shown in Fig. 4, and in some cases only a single trap iswanted at a particular place. The globe-valve case D is or may beprovided with suitable ears or flanges, b b, for securing it to a wallor other support. Thevalve-pipe B is mounted ,near its receiving end ina bracket, E, which is secured by screws at c or, other means to thewall or other support.

valve-seat when in contacttherewith. For the purpose of this adjustmentweemploy the construction represented or an equivalent means. a Asshown, it consists of a short sleeve or root larger pipe, G, fixed uponthe valve-pipe and screw-threaded on its periphery, soas to work in anaperture in the bracket E, which is screw-threaded, as a nut, to receiveit. In this screw-sleeve, near one end, there are pin-holes d d, bywhich to turn the sleeve and pipe for, producing the required adjustmentofthe pipe;

ting-box, H, which also connects or is joined in one, as shown, with oneor more stuffingboxes, I, by which the steam pipe or pipes K may bebroughtinto communication with the valve-pipe B. The expansion andcontraction of such steam-pipe in its stuffing-boxI are entirelyfreefrom, in action, and do not affect, the said valve-pipe. The valve-pipeBfor the second or any additional trap connected with the first is to bemounted, made adjustable, and connected with its steam pipe or pipes inthe same way asdescribed for the pipe B. The val ve-pipe B is perferablymade of copper, for obvious reasons,although we do notconfine ourselvesto any special material.

The section, Fig. 5, shows an adjustable valve-seat, A, for a singletrap, the seat screwing into the case and being held securely in anyposition to \vhichit is adjusted by ajamnut, g.

In Figs. 6, 7, 8 and 9 we show a construc- -tion of the trap by whichthe movement restill more sensitive and quick in its operation. We heremake the seat A also movable to ward and from the expansion valve-pipe13, and connect the pipe and seat by a lever or; other connection, sothat the lengtheningor; shortening movement of the pipe in expand ing orcontracting is communicated to the seat, multiplying the motion also, ifdesired, in such a-manner that-the movementsof thejpipe and seat areadded'tofproduce the effect of closing or opening the valvesthat is, thetwo ap-; proacheaeh other or recede from each other;

at the same time.

Referring to the drawings, the valve-pipe B;

andvalve-seat A are shown arranged'in line with each other, and the seatandone end of thepipe are mounted in packing orother ex- M, alsoproj ectfrom the case, on opposite sides of-the same, and from these lugs,respectively,f

.extendrods j j alongparallel'with the valvepipe'to a bracket or cla|np,E, which holds the outer end of the pipe. These rods extend through the;ends of the clamp, and are pro vided with adjusting-nuts k, by which the7 distancebetween-the clamp and-the trap-case is adjusted. The;pi pe Bis held'firmly by this clamp, a'clamp jaw or bar, I, being pressedrelation to the'valve-seat is adjusted in a manner equivalent to themeans shown in Figs. 1 and 4. The valve-seat A is or maybe provided witha screw-stem, a, to allow the said valve-seat to be located in just theposition desired. With this stem a lever, M, is connected .at one end,and may be adjusted in place thereon by adj Listing-nuts 0 0. The leverhas its fulcrum on an arm or a bracket, N, which is suitably mounted onthe trap-case D in the manner shown or otherwise. The other end of thelever is'pivoted to a connecting-rod,

O, which at the other end is connected with a clamp-piece, P, securedfixedly to the valvepipe B, as near to the trap-case D as practicahie,so as to obtain the advantage of as much of the expanding andcontracting pipe as possible for moving the lever M. The connecting-rodOmay be adjustable to different positions onthe lever, as shown by thedifferent pivot-holes .19 19, so as to multiply the motion transmittedfrom the pipe to the lever as much as desiredin its action on thevalve-seat A.

Any equivalent means of transmitting motion from the valve-pipe to thevalve-seat, so as to make them move in opposite directionsand toincrease their combined movements to the and held in position near itsother end andallowed a -free longitudinal movement atthat end, incombination with a solid plane-faced valve-seat, substantially as andfor the purpose herein specified.
